A little thieves oil couldn't hurt.
The story is that during the time of the bubonic plague, thieves would rob the dead and dying, and in order to protect themselves, they rubbed certain antibacterial oils on their skin (cinnamon, clove, rosemary, eucalyptus).
You can buy on Amazon, but you don't need the really expensive one.
In a spray bottle mix 8-10 drops with water and a little witch hazel (or few drops dish soap to emulsify). Spray in the air -- kills germs, and room will smell amazing 🙂
